In other words, experts can use a more efficient way to allocate their nervous resources. The purpose of the present study was to examine the relation between motor learning and the activity of brain areas. We assumed that the activity brain areas of high skill level would focus only on the areas related to the motor skill. To prove it, we designed a maze of narrow roads to compare the alpha power (8-13 Hz) of EEG data between one week’s practice. The rule of this test was not to touch the sideline. We encouraged the participants to finish the task as quickly as possible. The finishing time was the criterion to evaluate whether the participants improve their motor skill. Participants were two college students and the EEG was recorded at F3, F4, Fz, C3, C4, Cz, Fc1, Fc2, P3, P4, Pz, O1, O2, Poz, Fp1, Fp2, F7, F8, Fc5, Fc6, Pc1, Pc2, Pc5, Pc6 , T3, T4, T5, and T6 according to international 10-20 system. The result supported the hypotheses that the activity brain areas of high skill level focused to several brain areas. This phenomenon also supported the statement that experts use a more efficient nervous strategy to execute task than novices. Furthermore, the reason for the patterns of the two participants’ brain activity were different may result from that the practice time isn’t long enough, and the measurement isn’t sensitive enough to clarify the mechanism of central nervous system following motor learning.
